mentrykt, mod don indre Kant udbuet og tint cilieret, den 
ydre Kant forsynet mod on tydelig Afsats og gaaende ved 
Enden ud i en, uavnlig hos Hannen stserkt fremspringende 
konisk Fortsats, begge forsynede med en Del korte, pig- 
t'ormige Borster. lste Lsegled er noget indknebet ved 
Basis og successivt ndvidet mod Enden og har i Yder- 
kanten ilere smaa koniske, med pigformige Borster endende 
Fremspring, medens Inderkanten er fint cilieret og jevnt 
udbuet, starkest hos Hannen. 2det Lregled er adskilligt 
smalere, med Inderkanten nsesten lige, og har i Yderkanten 
en hoi Del grove pigformige Borster, hvoraf is an- en, fsestet 
noget forbi Midten, udmserker sig ved betydelig Lsengde. 
Det terminale Afsnit er lidt kortere end 2det Lsegled og 
meget bevsegeligt forbundet med samme. Dets lste Led, 
eller Tarsalleddet, er sserdeles lidet, nsesten skaalformigt, me- 
dens Fodleddet er overordentlig kraftigt bygget og noget ligt 
samme hos Phoxichilidium. Som hos denne Slrngt er det 
temmelig staerkt krummet, navnlig hos Hannen, omtrent 
af ens Tykkelse overalt, og i Inderkanten bevsebnet med 
Here korte Torner, hvoraf de 3 basale udmaerker sig ved 
betydeligere Storrelse. Endekloen er omtrent halvt saa 
lang som Fodleddet, meget kraftig og leformigt krummet. 
Bikloerne er vel udviklede og omtrent af Kloens halve 
Lsengde. 
De ydre HEgmasser er af uregelmsessig Form og inde- 
holder talrige temmelig smaa -Eg. 
Alle Integunlenter er sserdeles stserkt chitiniserede, 
navnlig paa Lemmerne, men dog noget gjennemsigtige, saa 
at Tarmen med dens blindsEekformige Forlsengelser skinner 
tydeligt igjennem hos det levende Dyr. 
Farven er mere eller mindre intenst gulagtig. 
Forekomst. Jeg har truffet denne Form enkeltvis 
paa Here Punkter ved vor Vestkyst (Espevser, Bekkervig, 
Korshavn, Kalvaag), hvor den forekom mellem Alger og 
Bryozoer paa 10 — 20 F. D. 
Udbredning. Arten er aabenbart en mere sydlig 
Form og er, foruden ved Norges Yestkyst, kjendt fra de 
britiske 0er (Hodge), Vestkysten af Frankrige og Holland 
(Hoek) og Middelhavet (Dohrn).

Artsclxaraeter. Legemet tykt og uuderssetsigt, med 
alle Kropssegmenter sammenvoxne. Sidefortsatserne for- 
holdsvis kortere end hos foregaaeiule Art, hver ved Enden 
forsynet fortil med en liden borstebserende Fortsats, bagtil 
very broad in both sexes and somewhat compressed, with 
the inner margin bulging and finely ciliated, the outer 
margin furnished with a distinct projection and passing- 
out at the extremity in a, especially in the male, strongly 
protuberant conical process, both margins furnished with 
a number of short spiniform bristles. The 1st tibial joint 
is somewhat constricted at the base and progressively ex- 
panded towards the extremity, and has on the outer margin 
several small conical projections terminating in spiniform 
bristles, while the inner margin is finely ciliated and evenly 
incurvate, strongest in the male. The 2nd tibial joint 
is considerably narrower, with the inner margin almost 
straight, and has on the outer margin quite a number of 
coarse spiniform bristles, of which one especially, secured 
somewhat beyond the middle, distinguishes itself by its 
considerable length. The terminal division is a little shorter 
than the 2nd tibial joint and somewhat movably connected 
to it. Its 1st joint, or the tarsal joint, is particularly 
small, almost cupuliform, while the propodal joint is ex- 
tremely powerfully built, and is somewhat similar to the 
same joint in Phoxichilidium. As in that genus, it is 
pretty strongly curved, especially in the male, about equal 
in thickness throughout, and armed on the inner margin 
with several short spines, of which the 3 basal ones are 
distinguished by considerable size. The terminal claw is 
about half the length of the propodal joint, very powerful, 
and falciforinly curved. The auxiliary claws are well devel- 
oped and about half the length of the claws. 
The outer (egg-masses are irregular in shape, and 
contain numerous rather small ova. 
All the integuments are very strongly chitinised, espec- 
ially on the limbs, but still somewhat transparent, so that 
the intestine with its ccecal prolongations is distinctly seen 
in the living animal. 
The colour- is more or less intensely yellowish. 
Occurrence. I have met with occasional specimens 
of this form at several places on the West Coast of N or- 
way (Espevser, Bekkervig, Korshavn, Kalvaag) where it 
occurred among Algse and Bryozoa at a depth of 10 — 20 
fathoms. 
Distribution. The species is evidently a more southern 
form and is, besides from the West Coast of Norway, known 
from the British Islands (Hodge) the AYest Coast of France 
and Holland (Hoek), and the Mediterranean (Dohrn).

Specific Characters. Body thick and stout, with 
all the segments of the trunk coalesced. Lateral pro- 
cesses relatively shorter than in the preceding species, 
each furnished at the anterior extremity with a small
